Find the equation, Centre, vertices, co-vertices, foci, equations of assymptotes and eccentricity of the hyperbola traced by the points that moves so that the differences of its distance from (-4,4) and (-4,6) is 6.

At ground level g is 9.8m/s^2. Suppose the earth started to increase its angular velocity. How long would a day be when people on the equator were just 'thrown off'? Why is the expression 'thrown off' a bad one?

H= 1/2gt^2 V=gt

I think the question have mistake. I tried my best but the graph is not like hyperbola. The value of a is greater than c therefore, b is undefined

7.64*10^10 9.0625*10^-3 0 I'm not sure for the third one

R=ucos20 (usin20+squareroot u^2sin^2 20+2gu)/g

R=2u^2cos26sin26/g

i. The car which was ...... ii. On Friday.......cinema, when the light ...... iii. I don't know iv. I wrote .........letter, that made..... v. All the buses which. ......

-3x-y=11 *2 both sides -9x-2y=34 --> -6x-2y=22 -9x-2y=34 subtract second equ from the first --> 3x=-12 --> x=-4 Substitute -4 in the first equ --> -6*-4-2y=22 --> 24-2y=22 --> -2y=22-24 --> y=-2/-2=1

Oh sorry something went wrong

The answer is correct I was confused for a second

i. -3x^2+5x-12 ii. 3x^2-10 iii. r^2+6r+9

Thanks
